ARMADILLO |
The nine banded armadillo would make you think it is
left over from pre-historic times. However, it is a modern species with great adaptability. It is so successful that in some places it is
becoming a pest.
Armadillos are unique amongst mammals in having perfect
defence armour. As a result it would rather class as part of the family of
tortoise than mammals. It also has an almost primitive and clumsy manner. In
spite of all that the armadillo is one of the very few species which have great
adaptabilities and it even extended its range.
Armadillos only live in the American and their areas
reaching form Kansa, Missouri south, through Texas, Mexico, Panama, Brazil,
Argentina and Uruguay.
BIRTH
When they are born it has a leathery, pliable skin.
After a few weeks the skin starts to harden into a series of bony plates
sheathed in horn. As the Armadillo gets older it grows its nine-banded plates
to cover the whole body. The plates move in concertina-like arrangements.
Sometimes the animals have nine and sometimes eight plates. Articulated bands linking
rigid shield that encase its hips and shoulders. The head, tail and legs are covered by
smaller plates. The underside of the animals has no armour. When threatened the
armadillo pulls in its legs and presses its body onto the ground.
No doubt the armour is heavy and therefore the
animals can’t swim. If in the water it just sinks to the bottom. One advantage
it has that it can hold its breath up to six minutes. It had been seen to just
walk across the stream at the bottom. It
also is able to inflate its stomach and intestines with air and floats across.
NOCTURNAL
The armadillo sleeps by day and feed by night. It
eats a wide variety of food from insect, small mammals, reptiles, bird egg, nestlings,
fruits, succulent roots, fungi and even to carrion. The way of adapting helps it a lot to survive.
The animals find its food in the dark by scuttling
busily over the ground and stopping when it thinks it found something good to
eat. If it finds a buried prey it will dig with its long, powerful claws on its
front feet. At the same time it closes the nostrils to protect to get chocked
with dirt or dust. While it doing this it supports itself with it s hind
quarters and tail and scatter the sail away.
In the south the nine-banded armadillo eats mainly
on ants and termites like the other five species of armadillo. It breaks into
the nests and gathers the ants, eggs and larvae with it long sticky
tongue. With its furious appetite it can
clear whole nets in contract with the anteater which only eat a small portion
and let the nest recover to used for another meal.
BURROWS
As the night ends the armadillo stops searching for
food and goes into burrows for safety. One animal can dig a dozens of these
burrows right across it s territory. Therefore, it always goes to the nearest
burrow as the dawn breaks.
The armadillo will dig burrows complex and being a
low as 2to 5m underground. It has to
entrances and several chambers which are lined with grass and leaves. When it
goes into one of those burrows it usually covers the entrance with vegetation.
Sometime it shares it with another armadillo of the
same sex but mostly it is a solitary animal. Females are very protective of
their territory. Males are wondering over a wide range and sometime over
lapping with each other
Territories are marked with scent. The animal has
scent gland on its feet which deposits its scent as it walks about. When it
smells an alien scent it will retreat to it home territory unless it is looking
for a mate.
BREEDING
Mating is always in the summer but the time various
to according to the area they are in. The gestation takes some four months. It
also can occur that there is a delayed imp plantation of the egg which could
anything up to 14 weeks. The reason is to make sure the birth is the time where
plenty of food is about.
The implanted eggs normally split into four and
there will be identical quadruplets born. The off=spring will be fed on mother’s
milk for a few weeks and then she leads them to forage for food. They stay together as a family and sometime
brothers and sisters live in a burrow without their mother. After a year they
definitely split and find a territory for themselves.

INFORMATION
The armadillos’ ancestors were giants. They had shells
up to 3m long. They survived up to 20,000 years ago. It was also discover that
their shells were used as roofs by the people who lived at that time.
Since the number of bands on its body vary a great
deal this particular species is also know as the long nose armadillo.
